Using vanitygen To generate addresses for different cryptocurrencies I know how to use vanitygen but how do you determine the number that will correspond to the -X parameter for a different cryptocurrency? For example it is -X 30 for Dogecoin.
I found some here. 


LTC: 48
FTC: 14
NVC: 8
ANC: 23
PTC: 47
CNC: 28
DGC:30
NMC: 52
PPC:55
YAC: 77
BQC: 85
IXC: 138
DOGE: 30


Proper syntax for VanityGen is: (from this question)

Usage: vanitygen [-vqrikNT] [-t &lt;threads&gt;] [-f &lt;filename&gt;|-] [&lt;pattern&gt;...]
Generates a bitcoin receiving address matching &lt;pattern&gt;, and outputs the
address and associated private key.  The private key may be stored in a safe
location or imported into a bitcoin client to spend any balance received on
the address.
By default, &lt;pattern&gt; is interpreted as an exact prefix.

Options:
-v            Verbose output
-q            Quiet output
-r            Use regular expression match instead of prefix
              (Feasibility of expression is not checked)
-i            Case-insensitive prefix search
-k            Keep pattern and continue search after finding a match
-N            Generate namecoin address
-T            Generate bitcoin testnet address
-X &lt;version&gt;  Generate address with the given version
-t &lt;threads&gt;  Set number of worker threads (Default: number of CPUs)
-f &lt;file&gt;     File containing list of patterns, one per line
              (Use "-" as the file name for stdin)
-o &lt;file&gt;     Write pattern matches to &lt;file&gt;
-s &lt;file&gt;     Seed random number generator from &lt;file&gt;
