Presentation

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

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

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