U+1D561 "𝕡" Mathematical Double-Struck Small P Unicode Character
Unicode Version 17.0
U+1D561 "𝕡" Mathematical Double-Struck Small P is a stylized letter belonging to the Mathematical Alphanumeric Symbols block, used primarily in mathematical contexts to denote a specific set or variable with a bold or blackboard bold appearance. This double‑struck form, characterized by its thick vertical strokes and often associated with open or closed sets, is commonly employed in advanced mathematics to represent objects such as the set of primes, probability measures, or other specialized notation in linear algebra and number theory. Its inclusion in Unicode ensures that mathematicians and researchers can reliably display and exchange such symbols across different digital platforms without relying on font‑specific representations.
