A group or set of ten, particularly used in historical contexts or specialized nomenclature.
From Latin 'decem' (ten), related to 'decade.' Relatively archaic term that appears occasionally in historical texts but is largely superseded by 'decade.'
The word 'decine' is so obscure that it barely survives in modern English except in historical documents—'decade' completely won the linguistic competition, leaving 'decine' as a linguistic fossil.
