The difficulty is that you are asking for a list of 100 Million entries to be stored into memory. The following shows the memory needed for evaluations up to 10^7 In[1]:= Table[ ByteCount[Table[ Random[Integer],{10^n}]],{n,0,7}] Out[1]= {40,216,2024,4056,40056,400056,4000056,40000056} For 10^7 we need approximately 40 MB. 10^8 would need about 400 MB. Considering that the operating system uses some fraction of memory, you simply do not have 400 MB free. I am wondering what you are trying to do. Perhaps you can accomplish what you want in more of a step by step method. Without details I simply can't make any useful suggestions.
