Put into layman's terms, a transcendental number is one of those numbers with lots of digits after the decimal point that go on forever.
The most commonly recognised one is PI and most people know it to a few places, which is generally good enough.
However, in this series of caches the final locations are based on codes and transcendental numbers and you might need rather more digits than usual to find the final location.
The first few caches will be quite recognisable numbers but later caches in the series will become progressively more difficult and the codes used more obscure.
To add to the horror of this series will be some disturbingly unfunny math humour.
