flopToRiverAtLeastOneHitUnionFourCategories

Four out categories; inclusion–exclusion on card counts (pair/triple/four-way intersection sizes).

flopToRiverAtLeastOneHitUnionFourCategories(unseenAfterFlop: number, outsA: number, outsB: number, outsC: number, outsD: number, s01: number, s02: number, s03: number, s12: number, s13: number, s23: number, s012: number, s013: number, s023: number, s123: number, fourWay: number): number

Import​

const poker = require('poker-calculations');

ESM (Node):

import { createRequire } from 'module';
const require = createRequire(import.meta.url);
const poker = require('poker-calculations');

When to use​

Maximum structured overlap case: four out families with all pairwise, triple, and four-way shared card counts. Pair indices follow (0,1)(0,2)(0,3)(1,2)(1,3)(2,3) as documented in index.d.ts.

How to use​

// Toy: four small categories, mostly disjoint
const p = poker.flopToRiverAtLeastOneHitUnionFourCategories(
  47,
  4, 4, 3, 2,       // outs A–D
  0, 0, 0, 0, 0, 0, // pairwise shared
  0, 0, 0, 0,       // triple shared
  0                 // four-way shared
);
console.log(p);
