The number of structural isomers of alkanes are only accurate up to 6:
- Heptane is said to have
7
structural isomers, while according to wikipedia
Heptane has nine isomers
- Octane is said to have
11
isomers, while
Octane has 18 structural isomers

In the case of heptane,
only one of
C - C - C - C - C - C

C
C - C - C - C - C - C

C
is considered;
only one of
C - C - C - C - C - C

C

C
C - C - C - C - C - C

is considered.
These result in the 2 unaccounted structural isomers.
