 OFFSET 1,1 COMMENTS a(44) is currently unknown. LINKS J. S. Myers, R. Schroeppel, S. R. Shannon, N. J. A. Sloane, and P. Zimmermann, Three Cousins of Recaman's Sequence, arXiv:2004:14000, April 2020 FORMULA Let f(i) = A058183(i). Assuming A332584(n)>0, a(n) = f(A332584(n))-f(n-1) for n>1. - N. J. A. Sloane, Feb 20 2020 EXAMPLE For n=2, A332584(2) = 88, and the concatenation 2 || 3 || ... || 82 is   23456789101112131415161718192021222324252627282930313233343536373839\   40414243444546474849505152535455565758596061626364656667686970717273747\   576777879808182, which has 154 digits. So a(2) = 154. CROSSREFS Cf. A332580, A332584.
