4 Number of consecutive series in which Virat Kohli has scored a double-century. This is the longest such sequence, going past Don Bradman and Rahul Dravid who had done it in three successive series. Kohli's streak began on India' tour to West Indies last year.
1 Player who has more two-hundred-plus scores as captain than Kohli's four - Brian Lara made five. Bradman, Michael Clarke and Graeme Smith also made four two-hundred-plus scores as captain. For India, their previous 31 captains combined hit only four 200-plus scores.
3 India batsmen who have scored more 200-plus scores than Kohli's four. Virender Sehwag and Sachin Tendulkar lead with six two-hundred-plus scores each and Dravid made five. Sunil Gavaskar also made four. No other player has scored more than two two-hundred-plus scores for India.
1 India became the first team to score 600-plus in three consecutive innings. They made 631 in Mumbai and 759 in Chennai, in the last two Tests against England before putting up 687 in this match, their fifth-highest total.
3 Captains to score double-hundreds against Bangladesh, including Kohli. The previous two are: Stephen Fleming (202) in 2004 and Graeme Smith (232) in 2008, both in Chittagong. Kohli is the second India batsman to score a double-century against Bangladesh after Sachin Tendulkar's 248 not out in 2004.
1168 Test runs scored by Kohli this season, the most by any batsman at home in one season. The previous highest was Virender Sehwag's 1105 in 2004-05. Sehwag had scored those runs in 17 innings; Kohli bettered him in his 15th innings. Sehwag averaged 69.06 in that season; after the first innings in Hyderabad, Kohli averages 89.84 this home season.
3 Consecutive Tests in which India have had at least one batsman scoring a two-hundred-plus score. Against England Kohli scored 235 in Mumbai and Karun Nair 303 not out in Chennai, before Kohli's 204 in this match. There have been several instances of two two-hundred-plus scores in two Tests, the last of which was in 2013 against Australia when Cheteshwar Pujara and MS Dhoni did it in successive matches.
3 Number of double-century partnerships between Kohli and Ajinkya Rahane - the most by any pair since 2013, when they started batting together. All their stands have been for the fourth-wicket. They equalled Sachin Tendulkar and Sourav Ganguly's record for 200-plus partnerships for the fourth-wicket for India.
6 Number of players who scored over 50 runs in India's innings - the joint-most for them in an innings. This was the sixth such instance for India, and their first since 2009 against Sri Lanka in Mumbai. Five of the top-six batsmen scored in excess of 75, which is only the second occasion for India and the sixth for any team.
7 Instances of five bowlers conceding 100 or more runs in an innings, as was the case in India's innings. This was the first such occasion since Australia's innings in Cardiff in the 2009 Ashes, where the hosts' bowlers did the same.
