Presentation

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

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

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