Supplemental Mathematical Operators is a Unicode block containing various mathematical symbols, including N-ary operators, summations and integrals, intersections and unions, logical and relational operators, and subset/superset relations.
Block
Variation sequences The Supplemental Mathematical Operators block has nine variation sequences defined for standardized variants. They use (VS01) to denote variant symbols (depending on the font):
+ Variation sequences Base character Base +VS01 Description U+2A3C INTERIOR PRODUCT tall variant with narrow foot U+2A3D RIGHTHAND INTERIOR PRODUCT tall variant with narrow foot U+2A6C SIMILAR MINUS SIMILAR using lazy S U+2A9D SIMILAR OR LESS-THAN with similar following the slant of the upper leg U+2A9E SIMILAR OR GREATER-THAN with similar following the slant of the upper leg U+2AAC SMALLER THAN OR EQUAL TO with slanted equal U+2AAD LARGER THAN OR EQUAL TO with slanted equal U+2ACB SUBSET OF ABOVE NOT EQUAL TO with stroke through bottom members U+2ACC SUPERSET OF ABOVE NOT EQUAL TO with stroke through bottom members
