Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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