See A054871 for definitions and key links.
Sequence can be also be seen as a(0) = 3, a(1) = 12, a(n) = H_{n-1}(10,10) for n>1. - Natan Arie Consigli, Apr 22 2015; edited by Danny Rorabaugh, Oct 20 2015

EXAMPLE
a(0) = H_0(10,2) = 2+1 = 3;
a(1) = H_1(10,2) = 10+2 = 12;
a(2) = H_2(10,2) = 10*2 = 10+10 = 20;
a(3) = H_3(10,2) = 10^2 = 10*10 = 100;
a(4) = H_4(10,2) = 10^^2 = 10^10 = 10000000000;
a(5) = H_5(10,2) = 10^^^2 = 10^^10 = 10^10^10^10^10^10^10^10^10^10 = ... .
