I googled it and everywhere this question is asked but without answer.

Except for the 4 at the beginning, the other numbers are the stops on the Number 1 subway line in New York City. If one started at the Courant Institute and wanted to go to Columbia University, and walked (it would take about 20 minutes) over to the Christopher St. stop - about 7th St., these are the stops that the train would make. (Courant is at 3rd St. and Mercer.)

    Except that 28 St is missing. Perhaps one should take the A train from W 4 St and change to the 1 at 59 St / Columbus Circle. I think the stops on that route match the given sequence exactly. For reference: http://www.mta.info/nyct/maps/submap.htm2012-02-23
