 A275203 Hyperoperations using consecutive integers. 0
 1, 2, 4, 64 (list; graph; refs; listen; history; text; internal format)
 OFFSET 0,2 COMMENTS a(4) is too large to display. The number of decimal digits in (the number of decimal digits in a(4)) is approximately 64^64*log(64), that is, about 7.1*10^115. - Robert Israel, Jul 19 2016 LINKS Wikipedia, Hyperoperation FORMULA a(n) = H_n(a(n-1),n), where H_n is the n-th hyperoperation. EXAMPLE a(0) = H_0(null,0) = 0+1 = 1. a(1) = H_1(1,1) = 1+1 = 2. a(2) = H_2(2,2) = 2*2 = 4. a(3) = H_3(4,3) = 4^3 = 64. a(4) = H_4(64,4) = 64^(64^(64^64)). CROSSREFS Cf. A189896, A264930.
