### Times Tables in Binary

Binary Patterns and All That

Times Tables of Prime Numbers in Binary

The times tables of up to ten sequential prime numbers (excluding 1 and 2) expressed in binary.

This page finds prime numbers using Javascript. It includes a few optimisation techniques and it has a litle

rest now and again, to give the opportunity to stop the process, but in the higher number

ranges it gets progressively slower, and Javascript is not the tool for dealing with very big numbers.

But those shortcomings are somewhat beside the point, the purpose of this page is to take a look at patterns.

Note: the purpose of this page is to see intriguing patterns against a sequence of prime numbers expressed in binary, see Prime Numbers in Binary and Tertiary.

Generate Prime Numbers in Decimal Binary and Tertiary

Prime number sequences form a pattern that it is hard for our minds to get a grip on.

Probably no one has got a grip on what the pattern is yet. That’s in decimal. They form

a more intriguing pattern in binary, and something else happens in binary: we find that with a great many of

them, if you reverse the binary digits you get another prime number. A similar type of intriguing pattern appears in tertiary.

Note: the ordinal numbering starts from 1 at prime number 3. 1 and 2 are prime numbers too

so strictly the ordinals should be 2 higher. Add 2 to feel completely pure.
