### Pluperfect Digital Invariants

A Pluperfect Digital Invariants or PPDI aka Armstrong Number is a number which is equal to the sum of a power of its digits.

For example:

$153 = 1^3 + 5^3 + 3^3$.
$1634 = 1^4 + 6^4 + 3^4 + 4^4$.
$54748 = 5^5 + 4^5 + 7^5 + 4^5 + 8^5$

The largest ( known? ) PPDI is $$115 132 219 018 763 992 565 095 597 973 971 522 401$$ which is equal to the sum of the 39th power of its digits.

These facts belong to the realm of mathematics, of course. But we get rather close to what I call anti-mathematics: numerology.

As soon as you discard scientific rigor, you're no longer a mathematician, you're a numerologist.

Mathematics: is it the fabric of MEST?
This is my voyage
My continuous mission
To uncover hidden structures
To create new theorems and proofs
To boldly go where no man has gone before

(Raumpatrouille – Die phantastischen Abenteuer des Raumschiffes Orion, colloquially aka Raumpatrouille Orion was the first German science fiction television series. Its seven episodes were broadcast by ARD beginning September 17, 1966. The series has since acquired cult status in Germany. Broadcast six years before Star Trek first aired in West Germany (in 1972), it became a huge success.)
