COMMENTS

A rise is an index i such that d(i) < d(i+1); a fall is an index i such that d(i) > d(i+1). The sequences A296762-A296764 partition the natural numbers. See the guide at A296712.

EXAMPLE

The base-60 digits of 223381 are 1, 2, 3, 1; here #(rises) = 2 and #(falls) = 1, so that 223381 is in the sequence.

MATHEMATICA

z = 200; b = 60; d[n_] := Sign[Differences[IntegerDigits[n, b]]];

Select[Range [z], Count[d[#], -1] == Count[d[#], 1] &] (* A296765 *)

Select[Range [z], Count[d[#], -1] < Count[d[#], 1] &]  (* A296766 *)

Select[Range [z], Count[d[#], -1] > Count[d[#], 1] &]  (* A296767 *)

CROSSREFS
