If you have 8176 inodes per block group this means you have a block size of 1024. Basically the number of inodes in a block group is blocksize*8 (1 inode block bitmap). If you want to read 8177th inode, go to second blockgroup and read the group descriptor, find the block number of inode table and read the first entry from there. Hope that helps.
