I started a blog at MaplePrimes.
Since I don't use Maple anymore, it is closed now. It still should contain a lot
of useful code - unless it was deleted (as it happened with my web pages at UPenn,
Oneonta, Shepherd, and TTU.) Here is
a link to my other posts there.

The Orbit Method for Finite Groups of Nilpotency class Two of Odd
Order (dvi), 16 pages, January 16, 2000.
First, I construct an isomorphism between the categories of(topological) groups
of nilpotency class 2 with 2-divisible center and(topological) Lie rings of nilpotency
class 2 with 2-divisible center. Thatisomorphism allows us to construct adjoint
and coadjointrepresentations as usual. For a finite group G of nilpotency class
2 of oddorder, I construct a basis in its group algebra C[G],parameterized
by elements of g* so that the elements of coadjoint orbits form bases of simple
two-side ideals of C
[G]. That construction gives us a one-to-one correspondence between G-orbits in
g* and classes of equivalence of irreducible unitary representations of G, implying
a very simple character formula. The properties of that correspondence are similar
to the properties of the analogous correspondence given by Kirillov's orbit method
for nilpotent connected and simply connected Lie groups. The diagram method introduced
in my thesis, gives us a convenient way to study normal forms on the orbits and
corresponding representations.

Aleksandrs Mihailovs. The Orbit Method for Finite Groups (October 5, 1999). Was
presented on Wednesday, January 19, 2000, from 5:30 pm to 5:40 pm. at the AMS Session
on Group Theory at the Joint AMS/MAA Meetings in Washington, DC, January 1922,
2000.
For a finite nilpotent group G, I define (by an inductive procedure) a finite G-module
g* such that there is a one-to-one correspondence between G-orbits in
g* and classes of equivalence of irreducible unitary representations
of G. The properties of that correspondence are similar to the properties of the
analogous correspondence given by Kirillov's orbit method. For instance, if G is
the group of the upper-triangular unipotent n×n matrices with coefficients
from a finite ring A, one can choose the additive group of lower-triangular nilpotent
n×n A-matrices as g*, defining the action of G in g*
the same way as Kirillov did in his classical article. Using diagram method introduced
in my thesis, one can classify normal forms on the orbits and corresponding representations.I
discuss the generalization of that construction for other classes of groups as well.
In particular, for symmetric groups all the theory looks completely different from
the standard approach.
