If A = {{N1},{N2},...,{Nm}} with m even, then First[Transpose[Partition[A, 2]]] gives the desired list. --Lou Talman Begin forwarded message: From: Paul.Hanson@colorado.edu To: mathgroup@smc.vnet.net Subject: [mg10523] [mg10471] List Manipulation Organization: University of Colorado at Boulder Hola! Hope you're all doing well. If I have a list of n lists, and want to get rid of all the even ones how would I go about doing this? That is, {{n1},{n2},.....{2n}} converted to {{n1},{n3}...{2n-1}}. I tried using the various procedures in Wolfram's book, but nothing seems to work (ie, Delete, Take, etc.). Thanks for the help. Paul Hanson -- * * * * /\ */\* / \ / \ /\
