Some minor touches[edit]

I sorted the Topics, removed "Topic:" from each of the subdivisions' names, created a new Elementary Mathematics division to help reduce clutter, and fixed a couple other minor details. MichaelShoemaker 01:12, 3 February 2009 (UTC)

Most-perfect magic square[edit]

Dear friends,

I was on a long wikibreak. I started to work again on most-perfect magic square, see sandbox/squares, sandbox/squares (details), Values of the Chautisa Yantra_magic square and commons:project:Featured_picture_candidates/File:Magic square at the Parshvanatha temple, Khajuraho.png.
The informations are to large for a Wikipedia article. Please ket me know at user talk:Gangleri if somebody can cooperate in writing, proofreading, advising about these topics.

links at The On-Line Encyclopedia of Integer Sequences!

"most perfect magic square"
A151941 The number of most-perfect magic squares of order 2^m where m>=2.
searching the "all ones" sequences
I have some ideas about making a generalisation of the Frénicle standard form using Galois group (see Galois theory) and residuals (see Isomorphism, Automorphism) to show that there is only one "generalised esentialy different" most-perfect magic square
examples ilustrates some of the homeomorphisms

Best regards and greatings from Munich. Best regards

Where is a good place for collaborative research on work on filters and lattices?

Speaking of that, where is a good place for collaborative research in mathematics in general? DariusGoad (discusscontribs) 20:56, 12 August 2013 (UTC)

PDF Files and Audio Books , The Wiki3[edit]

I'm very much interested in Mathematics, maybe a bit more compared to other areas of Science.... Does anyone think it would be a bit more interesting if we could download or view online mainly pdf, or other file reading formats of the main subjects and.... if Wiki volunteers, would want creating general knowledge audio books of the main subject...

eg.... A Main book about science and another separate audio book of subjects included, and sub audio books on parts of the subject book and goes on....

and we can call it wiki3 or Media3 (MediaWiki+mp3)

Does anyone think that would work....
