Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 5 generators on 28 points:

(1,2,3,4)(6,9)(7,11)(13,14,16,17)(15,18,19,20);(5,6,8,9)(7,10,11,12)(14,17)(18,20)(22,25)(26,28);(5,7)(6,10)(8,11)(9,12)(13,15,16,19)(14,18,17,20)(21,22,24,25)(23,26,27,28);(5,7)(6,10)(8,11)(9,12)(21,23,24,27)(22,26,25,28);(5,6)(7,10)(8,9)(11,12)(13,14)(15,18)(16,17)(19,20)
