I noted a similar thing with the J code but didn't get as far, this prompted me to do some reading on Gauss(bored...)
well after some fruitless reading, I followed a link to a link and found this...
http://www.mathsisfun.com/numbers/convert-base.php?to=quaternarythere's a pulldown to switch between any given number of a code
The thing about the J code...it could be 5 bits 01234, or the empty column could just be a space and end up being 0123 for the rest.
I posted this in that other thread somewhere, but it could be useful also:
http://home2.paulschou.net/tools/xlate/That's a code convertor, but not numbers, it handles text as well, IE
Omeganuepsilon = 01001111 01101101 01100101 01100111 01100001 01101110 01110101 01100101 01110000 01110011 01101001 01101100 01101111 01101110
The J code, could be the conversion of a conversion, but I'm too tired.
