3/Historical Note

Historical Note on 3|$3$ (three)
The number 3|$3$ was considered by the ancient Greeks to be the first odd number, as they did not consider 1|$1$ (one) a number, as such.

They associated the number 3|$3$ with the triangle, with its 3|$3$ vertices and 3|$3$ sides.

It was believed by the Pythagoreans to be the first male number, being composed of unity ($1$) and $2$, the principle of diversity.

In addition to that, in the eyes of the Pythagoreans, 3|$3$ was in fact the first number, as in addition they considered that 2|$2$ was not a number either, as it had a beginning and an end, but no middle.

similarly considered 3|$3$ to be the first number, but his reason was that it was the first number to be increased more by multiplication than by addition: $3 \times 3$ is greater than $3 + 3$.

 * In the English language, the sequence (beloved of fairy tales) once, twice, thrice ends there -- there is no single word for "$n$ times" for any higher number.
