http://www.maplesoft.com/applications/view.aspx?SID=153852&ref=Feed
This Tips and Techniques article introduces Maple's facilities for working with finitely presented groups. A finitely presented group is a group defined by means of a finite number of generators, and a finite number of defining relations. It is one of the principal ways in which a group may be represented on the computer, and is virtually the only representation that effectively allows us to compute with many infinite groups.<img src="/view.aspx?si=153852/thumb.jpg" alt="Tips and Techniques: Working with Finitely Presented Groups in Maple" align="left"/>This Tips and Techniques article introduces Maple's facilities for working with finitely presented groups.

http://www.maplesoft.com/applications/view.aspx?SID=153841&ref=Feed
An easy-to-use Maple implementation of transport encryption has been presented. It allows encrypting any file with arbitrary extension stored in the used computer system. The encrypted file contains space, alphabetic and decimal digit characters and the following special characters !#$%&'()*+,-./:;<=>?@[]^_`{|}~. These 93 printable characters can be defined by the set {32, 33, 35, seq(i, i=36 .. 91), seq(i, i=93 .. 126)} of byte values. Therefore, the encrypted file can be not only securely transmitted over the internet as an e-mail enclosure, but also protected effectively against unauthorized access. The application encrypts the name of the plaintext file as well: this way, the kind of content of the plaintext file is hidden. The encrypted file is saved in the same folder as the plaintext file. The size of the encrypted file is about 22.3% greater than the size of the plaintext file. On encryption/decryption in the GUI Text Area the user will see exhaustive information about the performed task. On decryption, the encrypted file is removed. It is worth knowing that the secret key in the application is embedded. Thus, any user can install his own secret key in the application in many ways. For example, he can change the value of the variable skc and the value of the variable seed in the procedures fne and fnd. The presented applications fed479k.mw must have permission to save and to remove the processed files. For security reason the application worksheet fed479k.mw ought to be stored in the meticulously watched over pen drive.<img src="/view.aspx?si=153841/im.jpg" alt="Maple Implementation of Transport Encryption Scheme Using the Secret Key of Length 479 Bits" align="left"/>An easy-to-use Maple implementation of transport encryption has been presented.

In the `RFC 4648` document (http://www.rfc-base.org/rfc-4648.html) the commonly used base 64, base 32, and base 16 encoding schemes are decribed. The output file, encoded according to this document, is about 33%, 60% and 100% greater than the input file, respectively. The presented application uses the base value equal to 93, and now the encoded file is only about 22% greater than the input file. The application must have a permission to save and to remove the files processed. It is easy to use - the reader is informed which tasks are being performed for any selected option, namely, he will know the input file size and name, the output file size and name, the encoding/decoding rates.In the `RFC 4648` document (http://www.rfc-base.org/rfc-4648.html) the commonly used base 64, base 32, and base 16 encoding schemes are decribed.
