• a(n) = binomial(n-1,4)*n^(n-5).at n=10A053509
• Triangle T(n,k) of number of minimal 4-covers of a labeled n-set that cover k points of that set uniquely (k=4,..,n).at n=21A057965
• Periodic part of continued fraction for sqrt(n), encoded by raising successive primes to the terms. If sqrt(n)=c0+[c1,c2,c3...] then a(n)=2^c1*3^c2*5^c3*...at n=12A059903
• a(0) = 1, and for n > 0, a(n) = the least multiple of prime(n) such that the geometric mean of a(0) to a(n) is an integer.at n=5A095209
• A triangular sequence in which the Prime[n]^(2*n) is treated like a variable expansion: (1-Prime[n])^(2*n) with the base Prime[0] is defined as one (in the Goldbach tradition) to lower the coefficients: t(n,m)=(-1)^m*Prime[n]^(2*n - m)*Binomial[2*n, m].at n=29A141024
