a(n) = A110555(n+1,10). - Reinhard Zumkeller (reinhard.zumkeller(AT)gmail.com), Jul 27 2005
Product of 10 consecutive numbers divided by 10! - Artur Jasinski (grafix(AT)csl.pl), Dec 02 2007
In this sequence only 11 is prime - Artur Jasinski (grafix(AT)csl.pl), Dec 02 2007
With a different offset, number of n-permutations (n>=10) of 2 objects: u,v, with repetition allowed, containing exactly (10) u's. Example: a(1)=11 because we have uuuuuuuuuuv, uuuuuuuuuvu, uuuuuuuuvuu, uuuuuuuvuuu, uuuuuuvuuuu, uuuuuvuuuuu, uuuuvuuuuuu, uuuvuuuuuuu, uuvuuuuuuuu, uvuuuuuuuuu and vuuuuuuuuuu.
