This site is supported by donations to The OEIS Foundation.

 Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing. Other ways to donate

 OFFSET 1,1 COMMENTS T(n,k) shows how often k appears among the first A006116(n) entries of A198260. n and k are counted from 1: 2, 3,  2, 4,  8, 2,  2, 5, 22, 8, 24, 2,  2,  2,   2, 6, 52,22,150, 8, 24, 24,  72,2, 2, 2, 2, 2, 2, 2,  2, 7,114,52,740,22,150,150,1046,8,24,24,72,24,72,72,216,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2 The number of different entries per row is 1,2,3,5,8,12,16... The second column 2,8,22,52,114,240... seems to appear in other columns as well. Row lengths are powers of two (A000079). Row sums are the sums of Gaussian binomial coefficients (A006116).
