[seqfan] Need help finding prime index values for sequence A363381

Good day all!
Sequence A363381 has a conjecture for prime indices that works for primes
3, 5, and 7 but is unknown for larger primes. My programming skills and
mathematical depth have stymied my attempts to encourage further
exploration or find a conjecture-busting counterexample.
The gist of the problem is to take an n X n array and break it into n
identical n-cell subsets with allowances for rotations, reflections, and
translations within the array.
The conjecture is that for a p X p array, there is only one way to break up
the array into p identical p-cell subsets. That is by breaking the p X p
array into p, 1 X p
subsets. If it does work for primes (proof?) it'd be really neat.
Any help would be appreciated!
