  Advances in Applied Mathematics, vol.21, no.3, pp.343-380, (October-1998).

Could someone check which sequences given on
p.377 are missing in the OEIS?

At least 1,1,2,7,17,50,131,363,924,2380 is missing.

When entering the seqs please spell out the symmetry type
(I cannot do this, that's why am asking on the list).

Best,  jj
