For your info, my input file format was as follows:
554.3=432
554.2=264
554.1=96
555.3=452
555.2=284
555.1=116
556.3=488
556.2=320
556.1=152
557.3=340
557.2=172
557.1=4
558.3=356
558.2=188
558.1=20
559.3=108
559.2=276
559.1=444

...
Firstly, the Perl one-liner posted earlier will *not* work for groups of 6 lines. It works *only* for groups of 3 lines.

Secondly, it may be beneficial if you could post some test data for groups of 3 lines as well as 6 lines. And post the output as well that shows what exactly is to be done for each group.

The input you've posted above is difficult to comprehend because it does not have the blank line that separates one group from the other.
