Nemeth Factorial Symbol

I would like to verify what the Nemeth Factorial Symbol is.

In looking at the Nemeth Code for Mathematics and Science Notation under Rule VI, Section 44 Exclamation Point: It says that the exclamation point is represented by the same sign of ink print as the factorial sign. The context is usually sufficiently clear in regard to this distinction so that the possibility of doubt in choosing the proper symbol is small.

I may be misunderstanding what it is saying but I believe it means to use the normal exclamation point dots 2,3,5 as the Factorial Symbol.

However I have found 3 other references that say the Nemeth Factorial Exclamation point should be written as Dots 1,2,3,4,6.

I want to verify that I am doing this correctly for my student. If you could please reply back to braillistrock@gmail.com I would very much appreciate it. As my student needs this information for early  next week, April 29, 2004.

thank you so much,

Debbie
