 OFFSET 1,1 COMMENTS The second, third and fourth terms a(n), n=2,3,4 are dimensions of certain Nichols algebras (quantum symmetric algebras) for which the generating space has dimension prime(n). LINKS Table of n, a(n) for n=1..10. EXAMPLE a(2) = 3 * 2^2 = 12 because prime(2) = 3. MAPLE for n from 1 to 10 do ithprime(n) * (ithprime(n)-1)^(ithprime(n)-1) od; CROSSREFS Cf. A000040.
