73= 5*5!! - 5 + (5!!/5)
73= 75 - 5 + 3
73= 73

what does gamma(n) work out?
is gamma(n) = n!/n? or alternatively gamma(n+1) = n!?

gamma(n)=(n-1)!

So in this case:
gamma(5) = (5-1)! = 4! = 4*3*2*1 = 24

74=((5+5)*5) + (5!/5)
74=(10*5) + 24
74=50+24
74=74

progress means getting nearer to the place where you want to be...If you are on the wrong road, progress means doing an about-turn and walking back to the right road; in that case the man who turns back soonest is the most progressive man.

The last part of 87 should be 5!!/5, which I know you meant 'cause your next line shows it as working out to 3.

88=5!-Γ(5)-5-5!!/5
88=120-24-5-3

94=floor(5*5!!+Γ5-Γ5/5)
94=floor(75+24-4.8 )
94=floor(94.2)
94=94
I couldn't find a way to make the correct notation.
