Hi Anonymous 

Create a sample like this :

Then create a calculated column to group .

RANKX(FILTER(ALL('Table'),'Table'[GROUP]=EARLIER('Table'[GROUP])),[Index],,ASC)

Finally , create a calculated column to compare the ID .

True = 
var _1=SUMX(FILTER(ALL('Table'),'Table'[GROUP]=EARLIER('Table'[GROUP])&&'Table'[Index]=EARLIER('Table'[Index])),[ID])
var _2=SUMX(FILTER(ALL('Table'),'Table'[GROUP]=EARLIER('Table'[GROUP])&&'Table'[Index]=EARLIER('Table'[Index])-1),[ID])
var _minindex=MINX(FILTER(ALL('Table'),'Table'[GROUP]=EARLIER('Table'[GROUP])),[Index])
return
IF([Index]=_minindex|| _1= _2,0,  SUMX(FILTER(ALL('Table'),'Table'[GROUP]=EARLIER('Table'[GROUP])&&'Table'[Index]=EARLIER('Table'[Index])-1),[Group_Index]))

The fianl result is like this :
