>>12192808Assing each letter a number g o o g l e thats 0 1 2 3 4 5, now you have a base 6 system. You need 4 letter words so start adding lowest 4 digit number in base 6 thats 0001 and add 1 until you reach 5555, the answer is obviously 5555 in base 6 which is 1295 in base 10, however dont forget 0000 (which stands for gggg), its a valid combination so the answer is 1295 + 1 = 1296

In other words its
Using base(number of symbols in a word) , go from lowest 4 symbol value ( it is still 1 but just add actual 000 in front) to highest, to find all values and the number of values
