Triangle of Gaussian binomial coefficients [ n,k ] for q = 5. A22169

Number of sublattices of index n in generic 5-dimensional lattice. A38992

Triangle T(n, k, q) = ((1-q)/(1-q^k))*c(n-1, q)*c(n, q)/(c(k-1,q)²*c(n-k,q)*c(n-k+1, q)), where c(n, q) = ∏_j=1..n (1-q^j) and q = 5, read by rows. A172302
