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