• Let x(1)x(2)... x(2q) denote the decimal expansion of a number n with an even number of digits. The sequence lists the numbers n such that (10^q-a)*(10^q-b) = n where a is the number having the digits x(1)x(2)...x(q) and b is the number having the digits x(q+1)x(q+2)...x(2q).at n=9A245587
• Triangle read by rows: T(m,n) = number of ways of distributing n distinguishable balls into m distinguishable bins of size 5 where empty bins are permitted (m >= 1, 1 <= n <= 5m).at n=38A248847
