Dec 1 st at neck edge only on 2nd and foll 0 alt rows, then on 6 foll 4th rows, then on foll 6th row until 18 sts remain.
I am new to knitting and I am very confused by the above 
Welcome to KH!
That is a lot to get through. I find it easier to take it one step at a time. Where there is a 0 for your size, you can skip that step.
If you call the next row, row 1 then dec at the armhole on rows 1,2,3,4,5,6,7; then dec on rows 9,11,13 and 15 and finally on row 19.
For the neck edge decrease on rows 1,3,5,7,9,11,13,15,17,19 and 21. That should take you to 26sts.
Continue to dec at the neck only on rows 23,27,31,35,39,43 and 47 and finally on row 53.
Whew! It helps to keep track of row numbers and check them off as you work them.
Good morning salmonmac
I really appreciate your help and I am sure now of what to do – thank you for your time 
I have printed off your advise and will cross each row off as I complete them.
Take care
Kindest regards
