Properties

Appears in sequences

• Triangle read by rows: T(n,k) is the number of partitions of the set {1,2,...,n}, having exactly k blocks consisting only even entries (0<=k<=floor(n/2)).at n=37A124422
• Random walk in R^3: Numerators of the expected distance after n steps.at n=10A340002
• Square array read by antidiagonals upwards: T(n,k) (for n>1 and k>0) is the smallest k-digit prime p such that prevprime(p) appears as a substring in p^n; or -1 if no such prime exists.at n=33A383613
• Prime numbersat n=25401
