Garten and Knopp [7] introduced the notion of infinite iteration of Césaro (C1 ) averages, which they called H summability. Flehinger [6] (apparently unaware of [7]) produced the first nontrivial example of an H summable sequence: the sequence ﹛aii=1 where at is 1 or 0 as the lead digit of the integer i is one or not. Duran [2] has provided an elegant treatment of H summability as a special case of summability with respect to an ergodic semigroup of transformations.
