Leuchar55

Hello. My name is Leuchar55. If I forgot to add something to an article, just let me know on my talk page.

Leuchar pseudoprimes

I invented Leuchar pseudoprimes. Here's the formula.

$d=(a+2)(b+2)(3c)$

a and b are equal to any odd natural number.

c is equal to any odd Fibonacci number.

27 is the smallest Leuchar pseudoprime. The highest known Leuchar pseudoprime is 81.

The number 55 is not a Leuchar pseudoprime. It's actually supposed to be 33 RPM expressed in centihertz.
