The 599th beastly number is 220666. This is the smallest
case in which the sum of digits of a beastly number (22) is
less than the sum of digits of its beastly index (23). Is
there any example in which sums of digits are equal? [Gaydos]
(There is one curio for this number that has not yet been approved by an editor.)
