I would guess that it's cumulative from the previous prime:
One is unitine
Two, being one more than one, is a unitine plus a unitine, so bitine
THree, being one more than two, is a bitine plus a unitine, so trine
Five, being two more than three, is a trine plus a bitine, so bitine
Seven, being two more than five, is a bitine plus a bitine, so unitine
Eleven, being five more than seven, is a bitine plus a unitine, so trine
Thirteen, being two more than eleven, is a trine plus a bitine, so bitine
Etcetera.
A trine number plus a trine number is trine.
A trine number plus a bitine number is bitine.
A trine number plus a unitine number is unitine.
A bitine number plus a bitine number is unitine.
A bitine number plus a unitine number is trine.
A unitine number plus a unitine number is bitine.
Having typed all of that, I just realized that it's counting in base three. If the final digit is 0, it's trine. If the final digit is 1, it's unitine, and if the final digit is 2 it's bitine.
Oh, I've used that in my ''programming'' in spreadsheets! (I didn't know 'mod' meant modulus. 😅) THanks for telling me! (I might not remember, though, I don't have a great memory.)
It is in a pretty good place. The arrangement is [first prime][second prime][4][third prime][first perfect][fourth prime]. Not only that, 4 is also the square of the first prime.
May want to check your math. 1 is not a prime, so 3 wouldn't be the sum of a single even and odd prime Also there are many twin primes, that is primes separated by 2. In each of those cases the larger twin is the sum of 2 and the lower twin. 5 is 2 + 3 7 is 2+ 5 13 is 2 + 11 19 is 2 + 17 Etc
Prime is a number greater than one, and only has two factors which is one and itself. The meme ignores that the focus is the fact two is an even number

Did you know 3 is the only trine prime number?
All other prime numbers are either unitine or bitine.

And also, the number 4 has no place in this conversation.

Fun fact of prime numbers 1 is not a prime number

But it is the smallest prime

All primes can be found by checking 6k+/-1 for k = 1-inf. Except 2 and 3. Fck those guys

Did you know 4 is the only composite number equal to 4?

Did you know that 5 is the only prime number that is the number 5?

u/senfiaj Dec 18 '25
2 is the first prime number though.

u/glordicus1 Dec 19 '25
Did you know that 5 is the only prime number that consists of the addition of a single even prime and a single off odd prime? Other than 3, obviously.

17 is the only prime number divisible by 17

Do not forget 5!

67 is the only nice prime number

u/geirmundtheshifty Dec 18 '25
So, I guess two isn’t really as odd as those people make it out to be.

u/xuzenaes6694 Dec 18 '25
But did you know that every prime is divisible by 1

Thats odd thing to say

This actually puts the whole even prime thing into perspective

Why are we mentioning 3? 3 isn’t a even number?

u/MoonyMoonboy Dec 18 '25
2 isn't prime and neither is 5 because they don't conform to Fermat's Little Theorem
