Other potentially-valid combinations with <math>\lambda=1</math> include (99,14,1,2) and (115,18,1,3) but it is unknown whether strongly regular graphs with those parameters exist.{{r|mak}} The question of the existence of a strongly regular graph with parameters (99,14,1,2) is known as [[Conway's 99-graph problem]], and [[John Horton Conway]] has offered a $1000 prize for its solution.{{r|zd}}
