- They discovered on computer that only primorial $1$, $2$, $3$, $5$ and $7$ can be represented as the product of consecutive numbers, up to primorial $3049$.

- $(1): \quad$ The primorial of $17$, which the section discusses, is omitted from this sentence. It perhaps ought to start:
- Apart from primorial $17$, ...
- $(2): \quad$ The primorial of $1$ is generally accepted as being $1$. There are no two consecutive numbers whose product is $1$: $0 \times 1 = 0$, $1 \times 2 = 2$.
