• Number of n-step up-side self-avoiding walks on the lattice strip {0,1,2,3} x Z (up-side means that the walks move up and sideways but not down).at n=16A171858
• Semiprimes which are products of two primes each with half the number of digits, and which when split in the middle gives two primes; no leading zeros.at n=33A243749
• a(n) is the denominator of the maximum expected number of steps of a random walk on the square lattice until it lands on a mined lattice point, given that mines are placed on all but n points.at n=11A366999
