Morphology
The meaning is directly derivable from its parts: 'octal' specifies base‑eight and 'notation' denotes a system of symbols, so together they denote a base‑eight number system. This is a regular compositional compound (common across languages) and, assuming the learner knows both constituents, a B1 learner can readily infer the meaning.
Etymology
Octal notation comes from octal, a word that means 'eight', and notation, which is a way of writing numbers. So it refers to the number system that uses eight digits, from 0 to 7.
