Answer:
As the name suggests, a 'triple mutant variant' is formed when three mutations of a virus combine to form a new variant. In this case, the three mutations are:
A deletion and two changes in spike protein
Deletion of H146 and Y145
Mutation in E484K and D614G in spike protein
The 'triple mutant variant' is the second lineage of SARS-CoV-2 virus to be identified in India. It is being called 'B.1.618', and is mostly circulating in West Bengal.
Earlier, a 'double mutant variant' of the virus was detected in India. It was officially named as 'B.1.617'.
Explaining the new strain, Vinod Scaria, a researcher at the New Delhi-based Council of Scientific and Industrial Research's Institute of Genomic and Integrative Biology (CSIR-IGIB), in a Twitter thread said the earliest sequence of this variant was isolated on October 25 last year in samples collected from a patient in West Bengal.
Answer:
Viruses keep changing and their structure, known as mutation, also keeps changing. The more a virus spreads, the more it mutates. While most of the mutations are harmless, some of them can trigger changes in spike protein and thus, a matter of concern like the double mutation India’s dealing with at present. More and more evidence are emerging that imply that the this double mutation is behind the massive second wave of coronavirus in the country.

What Is Triple Mutation?
Simply put, a triple mutation refers to the variants which have three different strains, that have combined together to form a new variant. Mutations may lead to a variant being either to potent or less potent.
When it comes to mutations there are three things that we need to note:
How infectious is it?
How deadly it is?
Is it resistant to antibodies, which means, if a vaccine will work against this mutation?
So far, we don’t have the answers to these three questions because India doesn’t genome sequence enough to be able to prepare a database.
