Recently I finished my thesis, entitled "A dictionary of modular
threefolds" and dealing with modularity of Calabi-Yau threefolds. I
made extensive use of MECCAH to produce a large table of integer
coefficients of weight four newforms for \Gamma_0(N) for N<=2430
(incomplete for large N).  I am attaching the thesis. It contains (at
the end of chapter 1) also my experiences concerning computing time
and memory.

The table was created between June 2003 and November 2004.  
Here is the table.  Each line contains a level and the first 25 coefficients
(up to a97}) of a certain cusp form of this level. In my thesis I
numbered the occurring newforms according to their appearance in this
list.  Whenever possible, I also mentioned the notation you started.

groups of elliptic curves as an application of results of Grigorov's

Hi William,

I just wanted to let you know that I'm using Meccah to do more 
calculations for an upcoming paper of Keith Conrad, Brian Conrad, and 
Harald Helfgott.

Thanks for making this all available to me.

November 2004 Edray Goins (Purdue) I'm computing the complete list of d-digit palindromes which are also d-digit palindromes for some base other than base 10. This list is in the range 1 < d < 27. I've written code in Mathematica which takes as an input two d-digit numbers N1 and N2, generates a list of d-digit palindromes N such that N1 < N < N2, and returns those N which are palindromes for some base other than 10. I'm using MECCAH to check several ranges {N1, N2} at once; I only need to check d = 17, 19, 21, 23, and 25 digits.
November 2004 Edray Goins (Purdue) I'm using gridMathematica (a parallelized version of Mathematica) to do a lengthy computation that requires a lot of computational power. The computation will use up to eight nodes total; several nodes will be at Purdue University, but MECCAH will be used for anywhere from two to six nodes from time to time. I plan to do most of the computation during the Thanksgiving break.
