This sequence is also a(0)=0, a(1)=1, a(n)=H_{n1)(4,4) for n>1.
LINKS
Table of n, a(n) for n=0..4.
EXAMPLE
a(0) = H_0(4,2) = 2+1 = 3
a(1) = H_1(4,2) = 4+2 = 6.
a(2) = H_2(4,2) = 4*2 = 8.
a(3) = H_3(4,2) = 4^2 = 16.
a(4) = H_4(4,2) = 4^^2 = 4^4 = 256.
a(5) = H_5(4,2) = 4^^^2 = 4^^4 = 4^4^4^4 = 4^4^256 = ...
