I am sorry, I posted this at 5 am or so my time and had not had any redbull yet =) here is what i meant to say: If (0,28,48,54,60,62,76,126) = (0000,1000,0100,1100,0010,1010,1110,0001) then you can encode the original array as:

[0000,1100,1000,1110,0001,0000,1000,1100,1010,1100,0000,1000,1100,0010
+,0100,0000,1100,1100,1010,1100,0000]

or as bits:

0000110010001110000100001000110010101100000010001100001001000000110011
+00101011000000

then convert to 12 bytes (filling the last 4 bits with 1111 to tag padding). to get the data back you need to chomp 4 bits per array slot until done or you hit 1111

0,54,28,76,126,0,28,54,62,54,0,28,54,60,48,0,54,54,62,54,0

stored in a file is 58 bytes. As long as the set of unique numbers stays fixed or less than 15 you can save space storing in this way and the larger the array the more savings you will see.

it was really silly anyways because you will note for such a small set the perl code to compress/decompress + the data compressed is larger than the starting data =)
