Clustering exactly 50 points using ArcGIS tools?

[SarahOvais]

I need to make clusters of exactly 50 points based on location to be used later as an input layer in VRP. No other attribute available on the basis of which they can be grouped. 
Grouping analysis doesn't give exactly the same no. Appreciate if someone can help. geonet geo-processing tools point statistics network geoprocessing vrp  networkanalyst

Nope, this is a feature class, I have replicated the same process. But, I still see few gaps in the output which shouldn't be there, like why is it picking few points from one cluster and few from another, while ignoring the other available (nearest).

Is there a chance that this is a multipart point file? (try multipart to singlepart tool)

[SarahOvais]

No It isn't. 
Any other solution for this?

Did you try a different setting? If peano is not giving an acceptable result, and since the data seems to be between UR and LL, you could try using that as a setting and see if the result is any better.
