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