Presentation

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

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

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