He started by dividing himself into 4 and then back into 1, and then doubled up to produce Sun, Sky, Earth etc. Followed by branching out plus 4 more high ones, plus 4 Companions dividing the many acts of creation.
The 4 Companions then added 4 Related ones = Whirlwind, Four Winds, Four Legs and Two Legs. Then came another 4 Godlike Ones which equals 16 into God knows what, all of which are divisible by WAKAN-TANKA as they retain a part of him to the value of W squared unless you know how to round it all up. He may even have Square Roots. This was all before Sales Tax, decimalization or the Euro.
He now manifests himself as the Great Thunder-Bird WAUKHEON, leading his flocks to battle against the demon watersnakes of darkness. There must surely be some thrilling music to go with it as they fly off in formation.
As a final summary, his name means Great Mystery. There is nothing we can take away from that.
