The best number on Google Voice

I got a GV invite today and had to choose which number I want. Of course all the repeated digits are gone (215-777-7772, ...) are gone. Google provides a simple interface to find a good number, but this is the interface I like, grep:

===So I did the following (Mac 10.5 / Safari)===

1. Download all available Google Voice phone numbers for a given area code.

2. Normalize the data:

grep -ho +1484....... *js | sort -u | cut -c 3- > numbers

3. Grep through to find the best numbers available (some example results shown):

# repetition

grep "\([0-9]\{4\}\).*\1" numbers

>> 4843248432

#pairs

grep "\([0-9]\)\1.*\([0-9]\)\2.*\([0-9]\)\3" numbers

>> 4842220022

>> 4842220044

# repetition

grep '\([0-9]\)\1\{3\}' numbers

>> 4849388886

# only 3 digits (mostly)

grep '^[483]\+.$' numbers

>> 4843344881

# palindromes

grep "\([0-9]\)\([0-9]\)\([0-9]\)\([0-9]\).?\4\3\2\1" numbers

>> 4846399364

>> 4842020248

# toggle

grep "\([0-9]\)\([0-9]\)\1\2\1\2" numbers

>> 4842020204

grep "484\([0-9]\)\([0-9]\)\1\2" numbers

>> xxx

# only two digits (except area code)

grep "484\([0-9]\)\1\*\([0-9]\)\(\1\|\2\)\{5\}" numbers

>> 4842020002

>> 4842020020

>> 4842020022

>> 4842020220

>> 4842220002

>> 4842220020

>> 4842220022

>> 4842220202

>> 4842220220

# more toggle

grep "\([0-9]\)\([0-9]\)\1\2.*\([0-9]\)\([0-9]\)\3\4\3" numbers

>> 4848580808

# the best

grep "\([0-9]\)\([0-9]\)\1\2\1.*\([0-9]\)\([0-9]\)\3\4\3" numbers

This is my new number. All the others are up for grabs.

Thanks for help from Chris Nolan who provided expeditious python scripting in support of this effort.
