The continued square root map applied to a sequence b(1), b(2), b(3), ... produces is defined to be the decimal number sqrt(b(1)+sqrt(b(2)+sqrt(b(3)+sqrt(b(4)+...)))).

sqrt(b(1)+sqrt(b(2)+sqrt(b(3)+sqrt(b(4)+...)))).

M. F. Hasler: certainly not a decimal number! Many related seq. should be XREF'd, e.g. A257574 and XREF there and A257764 and related.
