• Consider the triangle in which the j-th row begins with prime(j) and is the arithmetic progression with least common difference such that the remaining j-1 terms are composite and not divisible by prime(j). Sequence gives last term in each row.at n=39A095182
• Number of n X n arrays of squares of integers, symmetric about both diagonal and antidiagonal, with all rows summing to 68.at n=4A156523
• Number of compositions of n whose negation is not unimodal.at n=17A332669
• a(n) is the determinant of the 2 X 2 matrix whose entries (when read by rows) are the n-th primes congruent to 1, 3, 5, 7 mod 8 respectively.at n=27A337145
