Question 1203383
.


What the abbreviation MST means in your post ?



Also, what this term "all corners of the subdivision" means?



Usually, when Math problem is prepared by a professional Math writer, all the terms 

should be just defined in the problem's description before the question is posed 

- - -  it is a good style (and the only acceptable style) of writing Math problems.
