- "Binary undulants" are numbers of the form 2**N that undulate
- (alternate) the digits 1 and 0 in their decimal expansion.
-
- For example, 2**49 is the "highest quality" binary undulant so far
- discovered because it has the undulating sequence 101010 in it:
-
- 2**949 =

- Here N = 949 is called an undulation seed of order 6, since it
- gives rise to a 6-digit undulation pattern of adjacent 1's and 0's.
-
- Are undulation seeds of higher order easily found using either
- mathematical prowess or computation power?
