why one share trade??!!, page-3

From what I can see I think the CC trades for 24th Sept are

3.1 150,000 16:10
3.1 50,000 16:10
3.1 269,010 16:10
3.1 11,999 16:10
3.1 1 16:10
3.2 12,000 14:15
3.2 28,000 10:31


I think that this makes 471,010 (at 3.1c) at the close out of trading. The record does include a transaction of 1 share, but not sure what this means! A few possibilities come to mind - but I would just be guessing!
