Number
$2024$ (two thousand and twenty-four) is:
- $2^3 \times 11 \times 23$
- With $2295$, an element of the $5$th quasiamicable pair:
- $\map {\sigma_1} {2024} = \map {\sigma_1} {2295} = 4320 = 2024 + 2295 + 1$
- The $22$nd tetrahedral number, after $1$, $4$, $10$, $20$, $35$, $\ldots$, $816$, $969$, $1140$, $1330$, $1540$, $1771$:
- $2024 = \ds \sum_{k \mathop = 1}^{22} \frac {k \paren {k + 1} } 2 = \dfrac {22 \paren {22 + 1} \paren {22 + 2} } 6$
