• Generalized Pascal's triangle made using Mod[(Prime[n] - 1)/2, 4] == 2 primorial-like Stirling polynomials.at n=64A119724
• Triangle: signed version of A055134.at n=22A137370
• 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=10A141024
• Triangle read by rows: coefficients T(n,k) of a binomial decomposition of 1 as Sum_{k=0..n} T(n,k)*binomial(n,k).at n=34A244116
