ABC, ABD, ABE, ABF, ABG, ABH

ACB, ACD, ACE, ACF, ACG, ACH

ADB, ADC, ADE, ADF, ADG, ADH

AEB, AEC, AED, AEF, AEG, AEH

AFB, AFC, AFD, AFE, AFG, AFH

AGB, AGC, AGD, AGE, AGF, AGH

AHB, AHC, AHD, AHE, AHF, AHG

6 x 7 = 42 options with car A in first place.

you can go through and do the same thing with each car in first place...

BAC, BAD, BAE..... HGD, HGE, HGF...

But to do it mathematically ~ 8 cars, 42 options with each car in first place.

42 x 8 = 336 different ways eight cars can finish a race in first, second and third place.
