The ratio is 2:1. The frequency doubles for each octave that you go up.
Pythagoras discovered that musical intervals can be expressed in terms of simple numerical ratios. To create an octave, he found that if one string is twice the length of another, it produces a sound that is perceived as an octave apart. This means that the frequency ratio of the two strings is 2:1, allowing for harmonious sound. The ratio you mentioned, 21, seems to be a typographical error, as the correct ratio for an octave is indeed 2:1.

There is no antonym of octave. What could it refer to?
It seems there is a misunderstanding in the question regarding Pythagoras and the ratios of musical intervals. Pythagoras is known for his work on the relationship between string lengths and musical intervals, specifically the octave, fifth, and fourth, which are represented by simple whole number ratios. For example, a perfect fifth corresponds to a ratio of 3:2, while an octave is a ratio of 2:1. The interval you mentioned as "21" does not correspond to a commonly recognized musical ratio in this context.
when a number of ratios give the same answer after solving the ratios the ratios are said to be equivalent ratios

An interval of eight notes is known as an octave.

No, it's a diminished octave. There is no such thing as a minor octave.
There are 8 notes in an octave.

Eight notes in an octave.
The second octave of 200 Hz is 400 Hz. In music theory, each octave represents a doubling of the frequency of the previous octave.
The eight octaves in music are typically referred to as the following: Sub-contra octave, Contra octave, Great octave, Small octave, One-line octave, Two-line octave, Three-line octave, and Four-line octave. Each octave represents a range of pitches, with the naming convention usually based on the position of notes in relation to the grand staff. These names help musicians identify and communicate specific pitch ranges effectively.
octave is the name of a particular interval size
An octave is exactly 8 notes apart, so that each note comprising the octave is the same (eg an octave could be from C to C). The word "octave" is based on the root "octo", meaning 8.
Octave Berthier was born in 1875.
