this is perfect. the number you get using Chinese Remainder Theorem get pretty large, but all I asked is some way to assure me the existence of large holes.

What do you mean pairwise distinct? We have infinitely many prime numbers, so it's good. I am guessing you mean distinct along each row or each column ?

comment Groups of order $8n$ have at least five distinct conjugacy classes
@JasonDeVito OK. There could be any odd number of Sylow 2-groups, all conjugate to each other, which intersect each other in interesting ways.

@JasonDeVito Third Sylow theorem says the maximal Sylow $p$-group is normal. I stand corrected.
