The Amazing Story of the Ruth-Aaron Numbers
In all humility I hesitated to add this item to the collection. The mathematics is quite straightforward -- anyone with a passing knowledge of the transcendentals such as pi will immediately grasp. But first you have to get around the issue that in the United States a strange game called baseball is played in which Babe Ruth and Hank Aaron have a status akin to that of Don Bradman in a real ball sport. Even mathematicians in the US have a passing knowledge of this game. Now Babe Ruth's career regular-season home run total was 714, a record which Aaron eclipsed on April 8, 1974, when he hit his 715th career home run. So struggle on... Thus 714 and 715 are the Ruth-Aaron Numbers. Got it? Read on!

The mathematician, and baseball follower, Carl Pomerance, named the numbers 714 and 715 the Ruth-Aaron Numbers, after a student discovered that 714 and 715 had (different) prime factors with the same sum.
But there was far more to be discovered about the Ruth-Aaron Numbers:

Ivars Peterson made the amazing discovery that the sum of the Ruth-Aaron Numbers, 714 and 715, is a backwards-forwards-sideways prime:
In detail: 714 + 715 = 1429. This is a prime number -- its only factors are itself and(arguably) one. The claim was that if you scrambled the digits in 1429 in accord to the backwards and sideways concepts, -- you would still have a prime number. Thus:
So 1429, 9241, 1249, 9421, 4129, 4219 are all prime numbers.
As to 1492? That couldn't be more prime to an American who called the competition in which Ruth and Aaron played the World Series -- 1492 was the year that Columbus 'discovered' America.
What's more, 714 x 715 = 2 x 3 x 5 x 7 x 11 x 13 x 17 -- the product of the first seven primes. This must be the clincher !!
So we too accept Ivars Peterson's claim that 1429 is a backwards-forwards-sideways prime, on the basis of sufficient kutzpah.
