Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 6 generators on 20 points:

(10,12)(13,14)(15,16)(17,18)(19,20);(9,10)(11,12)(14,18)(15,19);(13,15)(14,16)(17,19)(18,20);(2,4)(5,6,7,8)(14,18)(15,19);(13,16)(14,15)(17,20)(18,19);(1,2)(3,4)(5,6)(7,8)(13,14)(15,20)(16,19)(17,18)

Polycyclic presentation:

2^10|d^2=g,b^a=bj,c^b=ci,d^a=di,d^c=di,f^b=fi,f^c=fi,f^d=fh,f^e=fi
